Vitamins are organic compounds and vital nutrients needed by your body to grow and develop in a profound way.

Vitamin E
Vitamin E, a fat soluble vitamin, consisting eight different variants (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) with varying levels of biological activity(2), found abundantly in corn oil, soybean oil, margarine, wheat germ oil, sunflower,safflower oils, etc. plays an important role in neurological functions and inhibition of platelet aggregation, regulation of enzymatic activity, free radical scavenger, etc..

    The Effect of Vitamin E on Cervical Cancer

According to the American Cancer Society's, in 2014, 12,360 new cases of invasive cervical cancer will be diagnosed with the death of 4,020 patients. The risk of cervical cancer is higher in Hispanic women followed by African-Americans, Asians and Pacific Islanders, and whites(1).
Epidemiological studies, linking vitamin E in reduced risk of cervical cancer have not been consistent(1a)(1b)(1c)(1d), but no doubt of its effectiveness in improvement of quality of life, through reduction of oxidative stress(2)(2a)

The Universidad Autónoma de Ciudad Juarez study indicated the effectiveness of dietary supplements, including vitamin E to reduced risk of cervical cancer but depending to the specific factors of the diseases(4)(5). The study from 1NationalCancer Center, of Korea, showed a strong inverse effect of antioxidants vitamin E against risk of cervical cancer in a 144 cervical cancer cases and 288 age-matched, hospital-based controls using unconditional logistic regression models(6). Tocotrienols, variants of vitamin E, including alpha-, beta-, gamma-, and delta- of palm oil in the testing against human cervical cancer cell line showed a strong effects of alphaT3 and gammaT3 induced cell death.through cell cycle arrest at G2/M phase and triggered apoptosis in a dose-dependent and time-dependent manner(7).
The Vilnius University study in the assessing the parameters of immune and antioxidant systems in patients with cervical cancer indicated a lower levels of antioxidant vitamin E and the activity of the antioxidant enzyme superoxide dismutase in comparison with the control group(8)(8a). Oral administration of alpha-tocopherol and quercetin, exerted their antioxidants effects in protection of DNA damage against free radicals through detoxification by increased glutathione and glutathione-s-transferase (9). The study at the University of Colorado Health Sciences Center of three human cancer cell lines, including cervical cancer (HeLa), indicated that d-alpha-tocopheryl succinate (alpha-TS) induced chromosomal damage in both human cervical cancer cells and ovarian cancer cells, but not in human normal fibroblasts in culture and enhanced the level of radiation-induced chromosomal damage in cancer cells, but it protected normal cells against such damage(10).

Taking altogether, without going into reviews, Vitamin E and its variants may have a protective effect in reduced risk of cervical cancer through its antioxidant properties. But further studies with large sample sizes and multi centers studies are necessary to validate its claims. Over doses of vitamin E supplement can cause symptoms of blurred vision, weakness, dizziness, nausea, diarrhea, etc., please make sure you follow the guideline of the Institute of Medicine of the National Academies.
